Itemsize mismatch Error

GNU Radio
1

Hello,

  I am building an application which involves sending data to audio
sink. The block ACS_premodulator_vff generates 1024 float samples and
audio_alsa_sink accepts 1 float sample . Error is as follows:

terminate called after throwing an instance of ‘std::invalid_argument’
 what(): itemsize mismatch: ACS_premodulator_vff(2):0 using 4096,
audio_alsa_sink(3):0 using 4
Aborted

can anyone suggest me how to make alsa_sink accept 1024 float samples ?

thanks for the help
Raman

Use gr.vector_to_stream in front of the alsa sink
